Weather the Worst: Tools That Keep You Safe and Ahead of the Storm

From moisture meters to voltage detectors, this essential gear can help you detect hazards and stay safe.

Severe weather preparedness is crucial because storm season is unpredictable, and when it hits, it doesn’t give you time to react. Whether you’re a homeowner, a facilities manager, or a field technician, having the right storm preparedness tools is essential for protecting property, equipment, and lives.

Each type of storm-related emergency demands specific tools and a proactive approach, from flooding and wind damage to gas leaks and electrical hazards. Fortunately, leading technology from FLIR and Extech makes that job easier, smarter, and safer.

From moisture detection and carbon monoxide monitoring to electrical hazard identification, FLIR and Extech offer industry-trusted solutions to help you detect danger, respond with confidence, and recover more quickly once the skies clear.

Moisture Detection Made Easy: FLIR MR277 & MR59

Storms bring water—and water brings problems.

Moisture intrusion from heavy rainfall, roof leaks, or flooding can lead to rot, structural damage, and mold growth, so early moisture detection is critical. That’s where the FLIR MR277 Moisture Meter with IGM™ and the FLIR MR59 Ball Probe Moisture Meter become your first line of defense.

The MR277 combines infrared imaging with moisture detection for pinpoint accuracy. Using FLIR IGM™ (see below) technology and a built-in thermal camera.

The MR277 reveals temperature differences that often indicate hidden moisture behind walls, under floors, or in ceilings. Once detected, you can confirm the presence of moisture using its integrated pin and pinless sensors, making it a true all-in-one solution.

What is IGM?

Infrared Guided Measurement, or IGM, uses the power of a FLIR Lepton® thermal imaging sensor to show you temperature differences across your target, guiding you to the precise location of potential problems that require further testing or investigation.

The FLIR MR59 is a ball probe sensor that allows you to scan large or uneven surfaces quickly, detecting moisture hotspots that would otherwise go unnoticed. Featuring Bluetooth capability, you can send valuable data directly to your phone or tablet via the FLIR Tools® Mobile app for easy documentation and real-time response.

With the FLIR MR277 and MR59, homeowners and pros have powerful tools to find and fix moisture issues fast before they become expensive repairs.

Monitor Critical Climate Conditions: Extech RH490

One of the most overlooked effects of storm season is the rapid fluctuation in temperature and humidity. These indoor air quality conditions can damage materials, trigger HVAC failures, and lead to mold infestations.

The Extech RH490 Precision Hygro-Thermometer is built to keep an eye on these critical indoor climate variables. With precision measurements of temperature, relative humidity, dew point, and wet bulb, the RH490 is vital for anyone managing sensitive environments.

From crawlspaces and attics to data centers and conference rooms, the RH490 helps you accurately monitor temperature and humidity levels to identify environmental changes that could lead to mold growth, equipment failure, or unhealthy occupant conditions.

With the RH490, you can measure hard-to-reach spaces, while the large, backlit LCD screen displays multiple readings at once. Data hold and min/max functionality help track trends over time, which helps when evaluating how a space is responding to storm-induced stress.

By giving you a detailed view of environmental conditions before, during, and after a storm, the RH490 helps ensure your space stays healthy, stable, and mold-free.

Breathe Easily Post-Storm: Extech CO10 & CO15

After a severe storm or hurricane, power outages often force homeowners and businesses to rely on gas-powered generators, grills, or portable heaters.

While these tools are essential for staying warm or powering critical devices, they can also introduce the risk of carbon monoxide (CO) poisoning. Because it’s colorless, odorless, and potentially deadly, having a reliable portable CO detector is essential for post-storm safety.

Extech CO10 and CO15 Carbon Monoxide Detectors are designed to provide quick, accurate detection of carbon monoxide in the air. Compact and portable, both models are ideal for storm preparation kits or emergency response.

The CO10 is a professional-grade detector that displays CO concentration levels on a backlit LCD, allowing users to monitor real-time levels with precision. The CO15 offers a simple, go/no-go LED indicator that alerts users immediately when carbon monoxide is detected at unsafe levels, which is ideal for quick checks in multiple rooms or confined spaces.

After a storm, these tools help you assess indoor environments where CO might accumulate, such as garages, basements, or poorly ventilated areas where generators or heaters are used. Whether you're checking a home, RV, or temporary shelter, the Extech CO10 and CO15 give you peace of mind by ensuring your environment remains free from harmful CO buildup. In a post-storm situation, when resources may be limited and conditions unpredictable, these detectors provide a critical layer of safety for you, your family, or your team.

Safely Detect Live Voltage: Extech DV690

After a storm, downed power lines and damaged electrical systems can pose serious hazards, even when they appear inactive. The Extech DV690 Non-Contact Voltage Detector helps you quickly and safely check for live wires or energized equipment without direct contact.

With a wide detection range of 100 V AC to 69 kV AC, the DV690 is ideal for identifying voltage in power lines, outlets, and electrical panels. A bright LED tip and loud audible alert signal when voltage is present, helping users stay aware even in noisy, low-visibility conditions. The built-in flashlight adds convenience when working in dark or debris-filled areas.

Compact and rugged, the DV690 is perfect for utility crews, electricians, and first responders needing a fast, reliable tool for storm recovery. It helps confirm whether an area is safe—minimizing risk and keeping teams protected in the field.

Identify Gas Leaks After Storm Damage: Extech EZ40

Storms don’t just knock out power, they can damage gas lines, fuel tanks, and appliances. That makes combustible gas detection a crucial step in any post-storm inspection, especially for those relying on propane or natural gas.

The Extech EZ40 is designed for fast, accurate detection of flammable gases like methane, propane, butane, and other substances like alcohol and gasoline. Its flexible gooseneck probe lets you "sniff" out leaks in tight spots, while an audible “tic” alarm and visual LED indicators intensify as gas concentrations rise, so you’re never left guessing.

Perfect for checking around generators, water heaters, furnaces, and damaged utility rooms, the Extech EZ40 gives you an early warning system for one of the storm season’s most dangerous threats.

Ensure Proper Airflow and Ventilation: Extech AN100

Even if your power stays on, storms can wreak havoc on your HVAC system. Blocked vents, flooded ductwork, or mechanical failures can all reduce HVAC airflow efficiency, leading to poor air quality, excess humidity, and mold risk.

The Extech AN100 gives you an easy way to evaluate airflow and air velocity across your home or facility. It measures airflow, air speed, and temperature—displaying it all on a large backlit screen. The built-in vane sensor offers reliable performance without the bulk or complexity of larger instruments.

With storm conditions often affecting airflow in subtle but serious ways, the AN100 is a smart tool for restoring comfort and safety as quickly as possible.
